Cyclo-oxygenase (COX) is a key enzyme in the conversion of arachidonic acid to prostanoids. The expression of its isoforms, COX-1 and -2 is found in many human malignancies. This study analyzed the correlation between COX expression and the pathobiological nature of human oral mucosa, dysplasias and squamous cell carcinomas (SCCs). We examined 9 specimens(More)
Recent reports have linked the expression of specific microRNAs (miRNAs) with tumorigenesis and metastasis. Here, we show that microRNA (miR)-16, which is expressed at lower levels in prostate cancer cells, affects the proliferation of human prostate cancer cell lines both in vitro and in vivo. Transient transfection with synthetic miR-16 significantly(More)
Human artificial chromosome (HAC) has several advantages as a gene therapy vector, including stable episomal maintenance that avoids insertional mutations and the ability to carry large gene inserts including the regulatory elements. Induced pluripotent stem (iPS) cells have great potential for gene therapy, as such cells can be generated from the(More)
In this study, we isolated and characterized a murine counterpart of the human Arpp (hArpp) gene. Sequence analysis revealed that the murine Arpp (mArpp) gene is almost identical to the Ankrd2 gene, which has recently been isolated as a mouse gene induced in stretched skeletal muscle. The mArpp gene encodes a protein of 332 amino acids that contains four(More)
Pulmonary metastases are the main cause of death in patients with osteosarcoma, however, the molecular mechanisms of metastasis are not well understood. To detect lung metastasis-related microRNA (miRNA) in human osteosarcoma, we compared parental (HOS) and its subclone (143B) human osteosarcoma cell lines showing lung metastasis in a mouse model. miR-143(More)
Since damage to DNA and other cellular molecules by reactive oxygen species ranks high as a major culprit in the onset and development of colorectal cancer, the aim of the present study is to clarify the role of antioxidant seleonoproteins including glutathione peroxidase (GPx), thioredoxin reductase (TXR) and selenoprotein P (SePP), and the effect of(More)
BACKGROUND AND AIM Multipotential mesenchymal stem cells (MSC), present in many organs and tissues, represent an attractive tool for the establishment of a successful stem cell-based therapy in the field of regeneration medicine. Adipose tissue mesenchymal stem cells (AT-MSC), known as adipose-derived stem cells (ASC) are especially attractive in the(More)
Runt-related transcription factor 3 (RUNX3) is a tumor suppressor factor of gastric cancer and appears to be an important component of the transforming growth factor-beta (TGF-beta)-induced tumor suppression pathway. This study aimed to analyze the expression of the RUNX3 protein in human oral normal epithelia, dysplasia and squamous cell carcinomas (SCCs),(More)
Early detection and treatment are critical in the management of renal cell carcinoma (RCC). However, there is no standard serum biomarker to facilitate early diagnosis or prognostic stratification in patients with RCC. Recent reports suggest that circulating microRNAs (miRNAs) have great potential as biomarkers for diagnosis and prognosis in patients with(More)
Arpp, a protein containing an ankyrin repeat domain, PEST sequence, and proline-rich region, is a novel ankyrin-repeated protein highly homologous to Carp, which is proposed to be the putative genetic marker for cardiac hypertrophy. In this study, we comparatively analyzed expression of Arpp and Carp protein in skeletal and cardiac muscles and(More)
